FAQ

Why choose Safety Gas Detection?

Because we offer much more than just our superb innovative products – a whole package to help you manage the life cycle of your gas detection needs. From survey and risk assessment of your application, through installation to maintenance and additional support services – all backed by a 5 year warranty.

I want to specify a system, what details should I include in my specification?

Because each application is different, contact us with some details and we will develop a tailored specification which we can send to you to incorporate in your own documents. This will ensure that you cover all the important aspects of procuring a suitable system.

Why do I need a fixed system when I can use portable personal monitors?

Fixed monitors operate 24/7 whether personnel are in the risk area or not, personal monitors operate only whilst the person takes the monitor into the area, and until the batteries need replacing/recharging

Fixed monitors provide indication of the risk before personnel go into the area, personal monitors require an individual to take the monitor into the risk area before a reading is taken

Fixed monitors can provide audible and visual indication of an alarm at multiple entries to a room, and over a wide area within a room using linked warning beacons, personal monitors can only indicate to people within close vicinity – especially in noisy areas

Fixed monitors can provide remote alarms to personnel via E-mail and SMS (especially useful for alarms during out-of-hours), personal monitors can not

Fixed monitors tend to be more reliable than portables as they are not moved around the work place, and therefore less susceptible to loss, damage and neglect

They generally constructed from more robust materials than personal monitors

Portable monitors are easily lost, misplaced and stolen

I’m not sure what type of system I need, can you help?

Of course. Do not hesitate to contact us – whilst we provide a high level of support to assist you in determining what is required to address your applications risk, we do not have a ‘hard sell’ sales approach. The quality and specification of our products and the level of support we offer provide all the sales technique we need! We can attend site and make a survey of your application, or alternatively for new projects inspect your plans and advise based upon these.

How many sensors will I need to cover an area?

There is no scientific formula to calculate this as it depends upon so many factors – the type of gas(es) causing the hazard, dimensions of the room, provision of natural ventilation etc. Contact our technical team who will be happy to advise or send someone to perform a no-obligation survey and assessment.

What gas types can you detect?

Anything that there is a sensor technology available including (but not limited to) Carbon Monoxide, Carbon Dioxide, Flammable Gas, Hydrocarbons, Oxygen, Refrigeration Gas and Toxic Gas

What do we do if the system gives an alarm?

If the system gives the full alarm, then we advise you to evacuate the risk area. You will need to install your own procedure to be followed in this event. All systems have a 1st alarm stage also, which gives indication before the full alarm is reached so that investigation and corrective action can be taken before evacuation is required.

What warranty do you offer?

All our systems come with a 5 year comprehensive parts and labour warranty – all that is required is an annual service to maintain your warranty. Beyond the 5 years, we can offer a ’no surprises‘ support package for a fixed fee, so you can manage your budget with confidence.

Who can install the system?

Systems are normally installed by our team, although we provide support for your electrical contractor or your in-house installation team should you prefer to use these. In that case, we can attend site once installation is finished to check connections, commission and test the system.

What if I want to monitor more than one room or building?

This is a standard feature of our systems, and individual zoned alarm outputs can be programmed to suit your application. We can even upgrade your system as circumstances change, adapting it in line with your requirements by adding or removing sensors and zones.

Can I connect it to my Building Management System (BMS)?

Yes, very easily using our standard alarm connections.

Where should the alarm system be fitted – inside or outside the risk area?

We always recommend fitting the User Interface outside of the risk area so that it is not necessary to enter the room to determine the status of the system. Warning to personnel inside the risk area is provided by alarm beacons which provide audible and visual indication in the event of a full (red) alarm. If for specific reasons you wish to site the unit inside the risk area, we have solutions to accommodate this also. The central control system is normally sited to accommodate wall space and ease of system installation.

Why do you not offer ‘off-the-shelf’ systems to buy online?

Because no two risks are identical. We take gas safety very seriously, as usually lives are at risk. We see our role as a supplier of a safety solution, not just an electronic product available from an online shopping cart. We like to be involved from the start to ensure that the product that is fitted is best suited to the application, and providing a support facility for the future.

I am storing a small quantity of Liquid Nitrogen, how can I calculate if the area is at risk?

It is necessary to calculate the room volume, and the volume of expanded Liquid Nitrogen, and then determine if the Nitrogen dispel enough air so the resultant Oxygen content would be 18% or less. To make this easy for you, we have a PC based calculation tool which we can send to you – simply insert the room dimensions and the quantity of LN2 stored and the tool does the rest. Alternatively, an even easier option is for you to send us your room dimensions and quantity of LN2 and we will send you the results.
